Abstract : The design of a permanent rocket-firing range to facilitate the determination of rocket trajectory data by cinematography, requires consideration of the location of camera stations and the direction of the optical axes of the cameras. This report discusses an advantage of opposing cameras whose optical axes are nearly prependicular to the rocket's line of fire. Part 1 introduces an estimate of the rocket's velocity for this case of opposing cameras, and examines its statistical worth. Part 2 contains remarks on the significence of this velocity estimate when the optical axes are parallel but not coincidental.
